T-slot Aluminium Profile From HOONLY

[chimpledfoothill]

In cold extruding, aluminum billet is pressed through the die at room temperature or near room temperature. Warm extruding, or forging, is done on billets brought to temperature ranges between 800 and 1800 degrees F. Hot extrusions are performed on aluminum which has been fully plasticized by heat and is often performed in a vacuum to avoid oxidation. After an aluminum profile has been extruded, it is straightened by a stretcher.
